Internet Explorer Plug-in for Webmail interfaces

[Ben]

I want to develop a plug-in software developed which works on OS -
Windows 98 and above and with IE 4.0 and above. This plug-in should
work with most web email programs, including Yahoo and Hotmail.

Here's the concept: When a user write an email in a webmail (like
yahoo or hotmail), and he types any email address in "TO, CC or BCC"
field and then clicks at any other place in the web page. The plug
in would add the extension – ".mydomain.com" at the end of all the
email addresses the user has typed.

For example – the user types (e-mail address removed) in the To field of
any web email program and clicks anywhere on the page (be it send
button, subject field, email body text field etc.) this plug in
convert this email ID to (e-mail address removed)

This ".mydomain.com" should be configurable by me but not by the end
user.

I'm generally working more on server-side projects and I'm pretty
new and "incompetent" when it comes to those kind of things. My
guess – I maybe wrong – is that it would use ActiveX. Am I right?
Now, can anyone clue me to get me started? Any idea to achieve that
kind of plug in? Thanks a lot in advance! Can't wait to read your
replies. Ben.

PS
Please note that it should work in classic webmails like Hotmail and
Yahoo.

What is the purpose here, other than writing a worm? Such programs (or
plug-ins) should be condemned, IMHO.

Brian,

I'm not in the hobby of doing worms and I condemn any worm attempts
too. I don't think real worm creators would post a request for help on
a microsoft newsgroup.
The users of this plug-in will fully, 100% be aware of what it does
and why. I wished i could tell you the deep reasons of this program
but i'm doing that for a company and as of now, i cannot tell. Now, i
would be delighted to explain you later on, once the project is
mature. You can always email me directly, now or later for more
details. As of now, would you have any advice on how to develop such a
plug-in ?

thanks
Ben
